// CSS image replacement//// Heads up! v3 launched with with only `.hide-text()`, but per our pattern for// mixins being reused as classes with the same name, this doesn't hold up. As// of v3.0.1 we have added `.text-hide()` and deprecated `.hide-text()`. Note// that we cannot chain the mixins together in Less, so they are repeated.//// Source: https://github.com/h5bp/html5-boilerplate/commit/aa0396eae757// Deprecated as of v3.0.1 (will be removed in v4).hide-text() {  font: ~"0/0" a;  color: transparent;  text-shadow: none;  background-color: transparent;  border: 0;}// New mixin to use as of v3.0.1.text-hide() {  font: ~"0/0" a;  color: transparent;  text-shadow: none;  background-color: transparent;  border: 0;}

有没有人用过这个？我在哪里指定要替换文本的图像？我是否正确地假设所有这一切都是隐藏文本而不是用图像替换它？

.my-image-replacement {  background-image:url('myImage.jpg');  .text-hide();}
